TYPE-WRITING MACHINE.

SPECIFICATION forming part of Letters Patent No. 400,200, dated March26, 1889.

Application filed March 3l, 1888. Serial No. 269,129. (No model.)

To all whom it may concern:

Be it known that we, JACOB FELBEL and ANDREW W. STEIGER, citizens of theUnited States, and residents of New York city, in the county of New Yorkand State of New York, have invented certain new and useful Improvementsin Type-IVriting Machines, of which the following is a speciiication.

Our invention relates more particularly to type-writing machines whereinthe t-ype are impressed upon an hiking-surface and caused to printdirectly upon the paper, and wherein a center guide is employed todirect all the type exactly to the same point, so that a perfectalignmei'it in the printing may be obtained.

The invention has reference to a mode of mounting the type barorcarrier; and it consists in pivoting it at one point to the free endof one pivoted link and at another point to the free end of anotherpivoted link, all as will be hereinafter more fully described, and setforth in the appended claims.

In the accompanying drawings, Figure l is a longitudinal verticalsection of a type-writing machine embodying our invention, many of thenecessary parts of the machine-such as feeding and spacing mechanisms,cbc.- heing omitted to simplify the view. Fig. 2 is a diagrammaticalview of the type-carrier and its connections, and illustrating themovements of the type to and from the printingpoint. Fig. is a detailview of a modification.

In the several views the same parts will be found designated by the sameletters of reference.

A is the base of the machine, at which are pivoted key-levers B B, thatare adapted to be operated in the usual way by finger-keys C C,connected thereto.

I) represents (in dotted lines) the paperplaten or impression-roller. Atthe printingpoint e oi' the machine is arranged a typeguide, E, adaptedto receive each type and cause it to print always at theimpressionpoint.

F is a type-carrier, preferably composed of a bar, f, having at one enda laterally-projecting arm, f', to carry the type G, and at the otherend a laterally-projecting arm, f2, bent in a direction opposite to thetype-arm f The type-carrier is pivoted at K (at the junction of the barf and arm f?) to one end of a link or lever, I-I, the other end of whichis pivoted to the frame or some stationary part of the machine.Preferably we pivot all the links or levers I-I at one end upon a wirering, I, which is supported from the base or some other iixed portion ofthe machine. In the drawings we have represented the ring or pivotalbearing I as supported by arms "i, branching from a pedestal or post, j,secured' to the base-plate of the machine. The typecarrier is alsopivoted at K2 (at the rear end of the arm f2) to one end of a link, Ii,whose opposite end is pivoted to the frame or some stationary part ofthe machine. By preference we pivot all the links L upon a wire ring, N,which may be supported by arms n n/,proj ecting from the post or columnThe link II is made to serve as the operating-lever by providing it withan arm or projection, h, on that side of its pivotal support opposite tothe pivotal connection with the carrierF. To this arm 71 pivoted aconnecting-rod, O, the lower end of which is attached to a key-lever, ascustomary heretofore.

IVe preferably arrange the parts so that the type-arms f will normallylie in a horizontal planewith theirends projecting radially of theprinting-point e and resting above the pivotal bearings of thetype-carrier; but the parts may be differently proportioned andotherwise arranged, so that the normal position of the type-carrier maybe different from what we have shown and just above given our preferenceto.

I) represents an in kin g-surface, so arranged that when the carriersare in their normal positions the faces of the type will touch the same.This inking-surface maybea circular pad of felt, which may be suppliedwith ink in any desired manner. The fulcrum-ringN is arranged centrallyof the machine and the links L radiate outwardly and downwardlytherefrom. The fulcrum ring or support I is arranged cxteriorly andconcentrically of the fulcruni N, and the links Il extend therefrom inradial lines inwardly and downwardly toward the links L. The inking-padis arranged above the fulcrum-ring I and between the latter and theplaten. The type stand above the links ll and L and their pivotalsupports or fnlerums and normally restI against the inking-pad.

The operation of the machine is as follows: llpon the depression of akey-lever, l, the rod is drawn down and the lever ll caused to turn onits bearing at l and swing upwardly. As the free end of the lever I lbegins to rise the free end of the link L begins to descend, and thetype-carrier connecting the two is slightly elevated and turned. As thevibration ol' the lever ll is continued theV link L begins to ascend,being carried up by the arm f2, and the type-carrier, moving about thepivots K K2, is finally caused to take a quarter-turn, the type (wtraveling in the curved path marked .1f in the dii'awings. lVhen thetype shall have arrived at the line y a further movement of the leverwill cause thecarrier to move in a nearly vertical direction, asillustrated by the dotted line y, until the type G reaches theprintingspoint, and, passing through the guide, strikes against thepaper on the platen or roller. Upon' releasing the pressure on theVlinger-key the typecarrier returns through the same path to its normalposition, and its type is caused to strike against the hiking-surfaceand take a supply of ink for another impression.

A spring, R., may be provided at any suitable point to return the partsto their first positions.

By arranging the links to vibrate in oppo site directions we are enabledto nieve the type in the shortest possible path to reacht-heprinting-point, and thus secure rapidity of action. In moving to theprintin g-point each type takes two welldeiined paths, being carriedfirst in substantially a horizontal direction to a point opposite theprinting-surface, and then in a direction substantially at right anglesto its Iirst path and perpendicular to the printing-snrface.

By varying the proportions of the several parts and the relativelocations of their pivotal points the track traversed by the type may bechanged, and we therefore do not desire to be confined to theproportions and arrangements of parts shown.

If desired,the inking-pad may be dispensed with and the usual ribboninterposed between the platen and the face of the type. So, also, maythe eenterguide be omit-ted; but the best results can be obtained by itsemployment.

Instead of the key-levers B and connectin g-rods, some other connectionsmay be provided between the finger-keys and the links II.

In lieu of lnoviding the link Il with an extension, 71, and vibrating itby pnllin g down, as illustrated at Figs. l and 2, the connecting rodAmay he attached to the link II in front ol' its pivotal support and thelink vibrated by an upward push, as shown in the modification exhibitedat Fig. l

The gist of our invention rests in pivoting' the typebarrier to the freeends of twohnks, as H and L, which vibrate in opposite dll-ections. Bythis arrai'igement the type-face is turned while traveling te thepi'intingpoint, and then caused to inove in a straight line and strikeperpendieularly to the platen, whereby the impression upon the paper maybe made without any liability of lllurrlng. By this arrangement thetype-face may also be presented perpendicularly to the inkmg pad orsurface when used, and thus secure a uniform and perfect supply of ink.V

In practice we have constructed and pro portioned the partssubstantially as shown, so that the type-:face is given a quarter-turnand presented perpendieularly to both the platen and the inking-pad, andthe results have been most satisfactory as to the inkm g and printingmechanism. i

By our invention. a superior type-writing machine ot' small dimensions,light weight, and great durability and speed maybe made at a very lowcost.

lVhat we claim as new, and d esirc to secure by Letters Patent, is-

il. In a type-writing machine, a typeearrier pivoted at one point to thefree end of one pivoted link and at another point to the free end ofanother pivoted link, the said links being arranged to vibrate inopposite directions and cause the type to move in two well-definedpaths, ii rst in substantially a horizontal direction radially inward tothe common center and then substantially in a straight line and axiallyto the printingsurfaee, substantially as shown and described.

2. In a type-writing machine, the combination of a eentrallyar-rangedfulcru11i-support, a series of links, L, radiating therefrom, aconcentric and extcriorly-arranged fnlcrumsupport, another series oflinks, Il, radiating therefrom toward thelinks L, and a series ol"type-carriers pivoted to .aid duplex series ofY radiating links Il andL, substantially as set forth.

3. In a type-writing machine, the combina tion of a series of pivotedlinks, H, extending inwardly and. down wardly, a series of links, L,pivoted nearer the center ot' the machine and extending outwardly anddownwardly, and a series of typecarriers consisting of the armsf f f2,disposed as described, and pivoted to the free ends of the links Il andL at the points K K2, substantially as set forth.

+L. In a type-writing machine, thc con1blna tion of a series ofinwardly-extending pivoted links, II, a platen above said links, acircular inkingsurface above said links and between them and the platen,a series of outwardly-extending pivoted links, L, and a series oftypccarriers, each pivoted at two points to the free ends of a pair ofsaid links, Il L, substantially as and for the purpose set forth.
